FIRE-HOSE Noz'zLE.

SPECIFICATION forming' part 0f Letters Patent NO. 660,147, dated October23, 1900.

Application filed December 27, 1899. Serial No.741j'713; (No model.)

To all, whom, it may concern:

Be it known that I, BENJAMiN CHAPMAN CRANE, a citizen of the UnitedStates, residing at Montesano, in the county of Ohehalis and State ofWashington, have invented a new and useful Fire-Hose Nozzle, of whichthe following is a specification.

The invention relates to improvements in fire-hose nozzles.

The object of the present invention is to improve the construction offire-hose nozzles, more especially that shown and described in PatentNo. 626,596, granted to me June 6, 1899, and to provide a simple,inexpensive, and efficient device adapted to be readily applied to anozzle and capable of arresting the rotary motion of a stream of waterand adapted also to serve as a guard or strainer to prevent anythingfrom coming in contact with the valves and clogging and interfering withthe operation of the same.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a longitudinal sectional view of a deviceconstructed in accordance with this invention and shown applied to thenozzle illustrated in the said patent. Fig. 2 is a transverse sectionalview. Fig. 3 is a longitudinal sectional view illustrating a slightmodiiication of the device.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

l designates a tube arranged within a casing 2, constructed inaccordance with the patent above referred to, and thel said tube 1,which is designed to be introduced into the said casing when theremovable side thereof is detached, is provided at its inner or rear endwith exterior screw-threads 3, which engage corresponding screw-threads4 of the interior of the extension or neck of the casing 2, as clearlyillustrated in Fig. l of the accompanying drawings. Theprojectiug'portion or neck 5 is provided with interior screwthreads 6for the attachment of a hose-pipe, and the said screw-threads 4,whichare smaller than the screw-threads 6, terminate short of the same toprovide a shoulder 7, against trated in Fig. 1 or the screw-threads ofany-` other ordinary fire-hose nozzle.

Within the tube 1 are arranged longitudinal partitions 9, crossing eachother at the longitudinal axis of the tube and disposed radially thereofto divide the said tube into quad rantshaped passages, as clearlyillustrated in Fig. 2 of the accom panying drawings. These partitions,which are adapted to arrest the rotary motion of a stream of Water, areslightly tapered or wedge-shaped, their sides l() being forwardly oroutwardly converged t0 conform to the configuration of the taperedinterior of the tube, whereby the said partitions are wedged therein,and the outward pressure of the water will operate to hold them inplace. Besides operating to counteract the rotary motion of the streamof water passing through the hose and nozzle the'device also serves as aguard or strainer attachment to hold in check anything which might clogand interfere with the operation of the valves. .The

partitions, which may be formed integral with each other or interlockedin any suitable manner, are readily removable from the tube when thelatter is detached from the casing of the nozzle.

It will be seen that the device, which is exceedingly sim ple andinexpensive in construction, is adapted to be readily applied to nozzlesand that it is capable of arresting the ro-v tary motion of a stream ofwater and of preventing the same from being broken up when it enters thecylindrical casing, whereby a straight stream of increased power iscaused to issue from the nozzle. It will also be apparent that besidesoperating to arrest this rotary motion of the water the device serves asa guard or strainer to prevent anything from entering the casing whichmight clog or interfere with the operation of the valves.

What is claimed isl. The combination with a hose-nozzle pro- ICO videdwith a cock or Valve and having screwthreads in rear of the saine,4 of adetachable device comprising a tube exteriorly threaded to engage thesaid screw-threads and located in rear of the cock or valve, andremovable partitions arranged Within the tube', said partitiopsbeingadapted to arrest the rotary` 1110.-4 tion of astream of Water andforming a guard or strainer to protect the cock or valve, substantiallyas described.

2. The combination of a hose-nozzle having a valve and provided withinterior screwthreads and having a shoulder in rear of the Ascrew-threads, a tube exteriorly threadedto engage the screw-threads andfitting against the said shoulder, said tube being located in rear ofthe valve, and partitions arranged Within the tubes, substantially asdescribed 8. The combination cfa nozz'le having a cock or valve, a-tubedetachably secured Within the nozzle and located ata point in rear ofthe cock or valve, said tube being provided with a tapering interior,Aand the partitions having tapered or converged edges and fitting withinthe tubeto arrest the rotary motion of a stream of Water and f'rming aguard or strainer to `prevent the valve or cock from becoming clogged,substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in `the presence of two Witnesses.

BENJAMIN CHAPMAN CRANE.
